Be good at what you do. Most people which are financially successful are not successful simply because they saved and/or invested.

They are good at what they do, first and foremost. They then take a portion of what they make and set it aside.

My suggestion is to save 10% into a 401k or similar plan. This makes retirement savings easier (you will need less because you trained yourself to live on less).

If you can save more than 10%, GREAT, but any realistic savings plan needs to account for at least 10% of gross pay.

The more you make, the higher this percentage needs to be, 10% is the base amount for starters.
