It seems most of us were made that promise of bicycle. One side it is good because it triggered you to study but another side, it can discourage you because broken promises can hurt terribly.
I believe that if you don't want to break a promise don't make one
You were also promised a bicycle 🤣🤣🤣
Yeah, I also use that moment to remind myself that anything is possible as long as I put my mind in it.
Simply say "I will try"
