Agree with most of the tips which they share, but please be reminded that is just about “What” we can do, we should also need to discover “Why” we do it. Or else, working so hard without a clear purpose will be very dangerous.
Beside that do aware of FREE, because without having the true purpose of acquire something, is greed, and that is dangerous.
Proverbs 1:19 So are the ways of everyone who is greedy for gain. It takes away the life of its owners.
