When things get hard the brain starts to come up with compromises to make things easier. If you stick to your guns and follow through then you will get more out of it than cutting corners or making compromises.
Do not follow someone you know is wrong. Do the work yourself to figure out what is right and what is wrong. Then always do what is right.
You are where you are because of the decisions you have made. Keep raising the standard of your decisions and what is acceptable. You have to look out for yourself first because if you don’t then no one will.
