A lot of energy gets drained by people challenges, personalities, minor issues.
A lot of it can be minimized by how you handle these matters.
Instead of tolerating differences, embrace and value them. Difference is the beginning of synergy, no difference no synergy. Diversity is actually a strength, not a weakness.
Look at the best possible interpretation of people and situations. Sometimes we misjudge others based on our paradigm. Everyone has a good side.
When you remain calm and centred, you will manage personality challenges well.
By keeping your ego in check and being non-judgmental you will make your life much lighter and happier.
