Motivating myself to eat more fibers, finding a way that works..

Recently I figured out I need to eat more fibers. It helps me prevent snacking, I crave sweet stuff much less, (perhaps TMI, but it improves my stool) and as a nice side effect, it helps with weightloss.

Now, knowing this and doing this are two seperate things. So I am bribing myself.. I am tracking my foodintake and only checking my fibers. For each day that I eat at least 20 grams of fibers, I get 2 punts. Every 5 point above those 20 grams gives me 0.5 bonuspoints. Every 10 points is worth money. My banking app has digital piggybanks, I give myself money for every 10 points and am saving up for a new e-reader. I have paid myself twice already in 10 days..
