1. Setting higher coding time without good resting time.
2. Failing to walk away for a while when bug get difficult to solve.
3. Watching programming videos and reading programming books more than practicing.
4.Failing to ask for help before getting frustrated.
5.Learning two or more languages at a time. dont ever try this last one because when you are learning a programming language be rest assure that you will be learning some related techs along side the programing language e.g sql, api, etc.
