100 good behaviors to practice?

You should set the bar a little lower maybe. Try picking up one new good habit per week or something. You'll just overwhelm yourself if you try to adopt 100 new behaviors at once and your chances of success will also be lower. Stay positive and trust the process.

Most people have their opinions about what is good behaviors from their standpoint. Children are guided by parent who express their own ideas based much on what their parents taught them and passed along.
If you wanted to repair an appliance in your home, would you hire a carpenter to fix it, or one who has expertise in that area?

Here is the answer to your question from the expert, the one who set the guide lines:
(Philippians 4:8) Finally, brothers, whatever things are true, whatever things are of serious concern, whatever things are righteous, whatever things are chaste, whatever things are lovable, whatever things are well-spoken-of, whatever things are virtuous, and whatever things are praiseworthy, continue considering these things. The things that you learned as well as accepted and heard and saw in connection with me, practice these, and the God of peace will be with you.

Hope this info is helpful
