3. There Is No Need to Please Others
If you are a mentally strong person, you are unlikely to try to live to please others. Do not worry if there are people who would like you to behave differently. Be polite and fair, but do not let others use you. Making others happy is not your job.
4. Look Forward to Future Events
Dwelling on the past might prevent you from moving on. Actually, thinking about what happened to you is just a waste of time. Spend your time on creating your future rather than mourning over your past. Make plans for the nearest few months or years. Your present is more important since this is the period of your life that matters to you and influences your further success.
