Happiness is about giving the self what it wants, while meaning is all about self-transcendence

 Happiness is about giving the self what it wants, but wants are never-ending. Each desire met is quickly followed by another desire unmet...this wanting continues...as wanting is a moving target. Desires tend to change, whether or not they’re gratified. Wants are inexhaustible 

Example: Destination addiction - the condition where you wait to reach some point in life to experience happiness. Next job, promotion, or a new relationship. It's never in the present. Always waiting for that future. It doesn't work. Find your happiness in your Present

Meaning is all about Transcending the self. Happiness may or may not give meaning but Finding our unique meaning in life with our creativity or any work will surely give happiness.

" Self-transcendence: it is the ability to look away from the self,

 from one’s own pain, one’s own circumstances, suffering, or grief.

 It is the ability

 1. To reach out to some other person or pursuing something greater that is worth dying for

2. To realize an ideal, or fulfill a task, and

3. To reach out to a Higher Being, to God, and in this process, one forgets about oneself.”
