Mannaz best translates into “realization".

The Mannaz  is good for you when you want to realize your full potential and reach it.

This is your rune if people are telling you that you’re wasting away your potential. Maybe you are not going after what you want, like your dream job that you would rather stay in your dead end job that you are comfortable in. The Mannaz will encourage you to step outside your comfort zone and realize what it is that you should be doing instead.
