How to Actually Build Real Confidence: Lessons from Sarzenco
Confidence is one of those qualities everyone wants, but very few people understand how it actually forms. In his recent 11-minute video titled Sarzenco: How to Build Confidence, life and personal development coach Sarthak Jain breaks it down in a refreshingly direct way: confidence is not a personality trait you’re born with—it’s trust you build (or destroy) through your own behavior toward yourself.
The core message hits hard right from the start: Confidence = Trust. And most of us are systematically breaking our own trust every single day without realizing it.
The Silent Trust Killer: Broken Promises to Yourself
Think about the last time you told yourself:
- “Tomorrow I’m definitely going to the gym.”
- “I’ll start waking up at 6 AM starting Monday.”
- “I’m going to stop scrolling and finish that project tonight.”
… and then you didn’t follow through.
Each time you break one of those internal commitments, you teach your subconscious: “I cannot be trusted.”
Sarthak compares it to a friendship. If a friend repeatedly promises to show up and flakes every time, would you trust them with something important? Of course not. The same logic applies to your relationship with yourself. Every unkept promise chips away at your self-trust → lower self-confidence.
The Foundation: Internal Confidence Comes First
The video focuses heavily on what Sarthak calls internal confidence (he promises a part 2 on external confidence later). Internal confidence has two main pillars:
- Alignment between thoughts, words, and actions
Especially in your self-talk. If you constantly say things like “I’m going to crush this” but then act in ways that scream the opposite, the dissonance creates self-doubt. The fix? Speak to yourself like someone you respect—and then back it up with matching behavior. - A strong, positive self-image
This isn’t toxic positivity or fake affirmations. It’s built through repeated evidence that you keep your word to yourself. Small, consistent wins compound. Decide → act → follow through → trust grows → confidence grows.
Practical Steps Sarthak Recommends
- Stop making promises you’re not 100% sure you’ll keep.
Be brutally honest about what you’re actually willing to do. It’s better to commit to 10 push-ups every day and actually do them than to promise an hour-long workout and skip it 5 days in a row. - Audit your conversations and environment.
Eliminate or reduce time spent in draining, low-value conversations and relationships that reinforce a weak self-image. Protect your mental space like you protect your bank account. - Reduce uncertainty through preparation and knowledge.
Confidence skyrockets when you know what you’re doing. Study, practice, rehearse—whether it’s public speaking, a job interview, a difficult conversation, or a new skill. Preparation turns “I hope I don’t mess up” into “I’ve got this.” - Make conscious, value-aligned decisions.
Act from your principles rather than impulse or fear. Each value-aligned action strengthens your internal identity.
Why This Matters More Than “Fake It Till You Make It”
The classic advice to “just act confident” can work temporarily, but it crumbles when you don’t believe your own performance. Sarthak’s approach is the opposite: build the internal belief first through consistent self-trust, and the external confidence naturally follows.
It’s slower than slapping on a power pose or buying a fancy outfit, but it’s far more durable.
Final Takeaway
If you want lasting confidence, stop looking for it outside yourself (validation, compliments, achievements). Start treating yourself like someone whose trust you desperately want to earn. Keep your word. Align your actions with your values. Prepare seriously. Over time, the evidence stacks up—and one day you realize you genuinely trust yourself.
That’s when real confidence shows up. Not as a mask you wear, but as a quiet certainty you carry.
