I agree with everyone one of the 16 pieces of advices listed here.
Here are two of my favorites, but please read the whole thing:
4. First, give value. Then, get value. Not the other way around.
This is a bit of a counter-intuitive thing. There is often an idea that someone should give us something or do something for us before we give back. The problem is just that a lot of people think that way. And so far less than possible is given either way.
If you want to increase the value you receive (money, love, kindness, opportunities etc.) you have to increase the value you give. Because over time you pretty much get what you give. It would perhaps be nice to get something for nothing. But that seldom happens.
5. Be proactive. Not reactive.
This one ties into the last point. If everyone is reactive then very little will get done. You could sit and wait and hope for someone else to do something. And that happens pretty often, but it can take a lot of time before it happens.
A more useful and beneficial way is to be proactive, to simply be the one to take the first practical action and get the ball rolling. This not only saves you a lot of waiting, but is also more pleasurable since you feel like you have the power over your life. Instead of feeling like you are run by a bunch of random outside forces.
