There are many and I mean many plans to chose from here. Don't wait, start now. It doesn't matter if you only have 1 minute or 2 hours. Start with something. I try daily to follow at minimum a 10-10-10-10-10 Rule:
- Read the bible For 10 minutes,
- Read a book for 10 minutes,
- Pray for 10 minutes, and
- Memorize Scripture for 10 minutes
- Write for 10 minutes
- Preach the Gospel for 10 minutes to yourself (of course evangelism would grow out of this discipline).
Of course each of these can be changed and or combined (for longer periods in one area) depending on your interests and time.
