To be more money smart. To sacrifice and save for bigger and greater things in the long run, as opposed to many smaller and insignificant things in the short term.
Also to have a contract in place from day dot and understand the terms. To actually seek a legal professional to have them draw it up and go through it with you so it represents what you want it to, and not some person put together and slapped on the internet for free. it will pay off in the long run!
