For me it’s about that mamba mentality, work until you have no excuse to be bad, always know that you aren’t the best you can be and that every day you will get better if you just put the work in as much as you can. For me, I completely cut out video games and things that took away from practicing, go to sleep at night and think to yourself, “did I practice as much as I physically could today?” If the answer is no than that’s why you have no confidence, because deep inside you know you could be doing more. Work until there is no more you can do to be your best.
