There are tricks that have the power to seriously improve one's life.
Certainly one got to check first about seriousness etc. but we speak with smart people who talk about practically relevant tricks.
Two mistakes are common and must be corrected.
1) Not maximizing the effect. Do not be "realistic" or conservative. Some new things you learn have the power to transform life for good.
Take it to the max (with prudence, for sure).
Many times there is way more potential than we think. We just have to be naive kids and take it to the most power possible.
2) Do not forget other things because of the new trick.
We collect through life lots of experience, decision rules, understandings etc.
It sounds tempting to think, that if for example we have a new trick to reduce stress, we can afford stress freely, or ignore other things to do to relax.
We must leave in place the good things we know etc.
Only after time and experience, we may use the new tricks to dispense of things that are no longer relevant.
If you change, it has effects all over the board.
There is a lot of dependency in life.
Much of our rules, understanding etc. are based on our experiences expectations about our behavior, expectations about experience and so on.
Once we change, we may take a quick look at our whole inventory and look whether everything is still relevant. Some things may no longer be useful, or are harmful now.
