Six Top Mindsets to Eliminate Inner Friction:

First, don't complain about what has already happened. Confront the facts; either work hard to change them or accept them calmly. Repeatedly dwelling on and complaining about the past only drains your emotions and energy, intensifying internal conflict.
Second, don't dwell on past mistakes. The past is already settled, like dissipated smoke. What truly matters is learning from it, then letting go and moving forward lightly.
Third, focus on the present and stop meaningless comparisons. Don't always envy others. The life you have may be exactly what others aspire to. Shift your attention back to yourself; managing the present well is the most solid happiness.
Fourth, learn to enjoy solitude. Time alone can be fulfilling and wonderful. Don't overly rely on others to fill the emptiness inside. The lifestyle you坚持的，可能也正被别人羡慕。
Fifth, don't expect everyone to understand you. Even those closest to you may not fully comprehend you. Learning to reconcile with being "not understood" is an important sign of maturity.
Sixth, believe in your power to change. No matter where you are or what circumstances you're in, you always have the ability to change yourself. Maintaining the courage to stay positive in difficult times, your strength is enough to alter the course of the future.
