This is pretty ambitous! We need more people like you!
However, if you are struggling with staying motivated, I fear this challenge of yours wont do you much good.
The key is to not "motivate" yourself, but to discipline yourself and realise that success is not something you attain by being "motivated" for the whole journey.
You need to discipline yourself and realise that true success wont happen in 6 months... Heck, not even in a year. If you discipline yourself enough, so that you begin enjoying the process - then and only then, will you attain the success you seek!
If you're interested in disciplining yourself, I will be writing up some posts about it in the near future!
All things aside, I do wish for you to succeed in this challenge of yours! Best of will!
