A huge part of success is accountability. Holding yourself responsible for your actions and choices speaks volumes to the type of education and upbringing you had, and is a determinant for how you set and achieve goals. This is true in any aspect of life, but it’s arguably easiest to observe in training and nutrition.
So you’ve made that first step by joining a gym. That’s great! You show up to class sort of consistently, albeit it always late, and you make an effort to ask the coach the finer details of building muscle, eating right, and training properly for your goals. But things just aren’t going your way because “life happens” and other things are to blame rather than yourself. Eventually, you fall off and blame the gym for your failure. We all know this person. Here’s the hard truth: everyone has things that are out of their control, everyone has the capacity to learn for themselves, and everyone has 24 hours in a day. It’s up to you to manage accordingly.
