In order to motivate yourself and strengthen your will for life, you must define your goal and what you want to achieve and reach success through it in your scientific, practical, social, and even psychological life so you have to be confidence in yourself and your will and be patient and your parents the following advice:
Set a goal in your life and try to achieve it by scientific and systematic methods
- Talk to yourself positively and make your perception of your personality always positive and keep negative thoughts away from your thinking
- Train yourself in how to deal with people and try to face people and do not be afraid and do not worry about that
- Always be optimistic and OK. If you fail at once or make a mistake, it is the fault that teaches the right path and illuminates the path of success and tries to change the paths, not the goal.
- Develop yourself, practice your hobbies, excel in it and show it before yourself and in front of people
- Mix the positive people in your life. Understand the cheerleader and the promoter of success for you, and stay away from the negative people. There is no need for them in your life.
Boost yourself after every success, take a picnic, and practice the thing you love
- Do not despair, do not despair with life, and life with despair
