"What you will do matters. All you need is to do it." - John Keats
Don't give up because it's hard.
Is it your passion? Is it what you love to do? Is it what makes you feel alive and connected with yourself (and others)?
Then keep doing it! We can serve others when we are at our best, and we are at our best when we allow ourselves to fully, simply be all that we are meant to be.
