Putting yourself first and taking care of yourself is never a bad thing. However, be very mindful today to not disregard or have conflict with others while thinking of your own interests. When too much ego comes into place, you lose sight of the highest good for all and others emotions or feelings.
Perhaps you feel hurt by a circumstance or person, but try to not lash out in such a way that you will possibly regret it later on. Meditate, do breathing exercises or just try to see things objectively, from a different perspective and without judgement.
Sometimes it’s not just about being right or wrong, but doing what’s best for yourself and everyone around you. Fill yourself with love and understanding.
