Patience:
It's not only about enduring during the workout but much more: doing research, making a diet plan, trying the exercises which suit me the best...
The most terrifying part must be doing the research at the beginning, because it's basically "learning from scratch" on my own.
Instead of just using the routines (which already included diet plan, exercises,...) provided by other experienced bodybuilders, I decided to learn everything and build it myself.
It was much more difficult than I'd thought, plenty of questions popped in my head: Why should we focus on protein-carb-fat?
Should I do dropsets or regular sets?
What's the best frequency?
Why is this exercise the best by this fitness guru while some others said it's not?? etc...
I've almost given up at that point .But then I thought: "If I manage to understand all of this, I'd not only do them well but could also find and fix my mistakes and avoid falling into confusion".
Bit by bit, I've finally achieved what I'd aimed for.
Not only I can figure out how to fix my errors (which I wasn't able to) but I can improve my workouts as well thanks to my strong knowledge base in lifting.
Everything seems so clear now comparing with 1 year ago.
And from that, I've learnt another truth about "being patient":
Being patient is not about keep on doing the same thing which you already get used to do.
It's about how you keep moving forward despite how tiresome and disheartened you feel.
