Excellent. However I would advise you not to be too stringent or hard on yourself. Don't focus on renouncing your simple pleasures in life. Just focus mainly and sincerely on helping others, and with the intention of doing it for God. Opportunities for charity abound, as there are many underprivileged people. You can do volunteer work, and definitely make a plan to donate money or food to the needy.
Just keep trying to be helpful, and yes, you will encounter discouraging people on the way. Don't let them dishearten you.
All the best!
