Where there is a will, there is a way

उत्साहो बलवानार्य
नास्त्युत्साहात्परं बलम् ।
सोत्साहस्य च लोकेषु
न किञ्चिदपि दुर्लभम् ॥

Enthusiastic person is always powerful. There is nothing stronger than enthusiasm. Nothing in this world is impossible for an enthusiastic person.

Where there is a will, there is a way.
Nothing great was ever achieved without enthusiasm.
It's faith in something and enthusiasm for something that makes a life worth living.
