Don’t think that you are insignificant. We all have a special role to play in this world. Discover and know that calling. Follow that calling.
You will undergo trials, difficulties, and failures. There is always a temptation to go back to the old way of life, old habits, and to jump ship. But, the Lord meets us in our failure and he challenges us to get back to his calling and live for his kingdom.
I have competed well; I have finished the race; I have kept the faith.2 Timothy 4:7
Remember failure is success in progress. Stay the course, finish the race.
