Saving for your 401k. Max that out in your 20s. Do not make this mistake, you can never catch up!
I always took it for granted when I was younger because I was naturally in shape so I never took it seriously.
But then working on a computer and getting older made me gain a fair amount of weigt.
Fad diets and Fad exercise and Fad weight loss programs are all temporary and not that effective in the long term. Physiological health requires long-term maintenance not a temporary fix.
I think it's imported to get into a regular exercise habit as soon as possible and just make it a part of your daily life. You have time to figure this out in your 20s and it will pay off dramatically when you get older.
I highly recommend hiring a personal trainer for at least a few months to teach you proper form and theory and get you into a regular routine.
It has changed my perspective on exercise.
Highly recommended and 100% agree with this post.

That kids are important of a person's life is a lie sold to the public. Sure if you want to have kids have them but not everyone should feel compelled. Kids costs hundreds of thousands of dollars not to mention the tangential background impact on your life of always having to worry about money and their well being.
If there are people reading this who don't want to have kids, don't feel bad. It is your choice to make!
