Fitness is a subjective term. So use it to your advantage to define what that is for you. For sure, it involves being healthy and sharp. But on top of it, how do you see it? What does it mean to you? Define it. Set an aim. Chart a course of action to gradually get there over time. It has been a game changer for me.

I don't do weights (though I love it) except for little bit of good old DB Bicep Curls and DB Lateral Raises from time to time in addition to my bodyweight training regime. I enjoy calisthenics aka bodyweight exercises mostly. I aim for advanced Calisthenics movements. That is something that works for me. Find out what works for you.

Naturally, the first question to ask yourself would be- Loser at what? Take the time to define 'loser' for yourself. We all are loser at most things. We could only be a winner at only very very few things in life. And that, too, required tremendous focus, hard work, patience, and planning. 

Know your argument well before you engage in tough conversations. Otherwise, you'll only try to win instead of trying to meet the required objective.
