Regardless of how you feel, stick to the plan. 

Refuse to make excuses. Create the reality you want.

Most will allow themselves to end the day with a pat on the back, knowing good and well there are many stones they left unturned. Use this as a reminder to do all that can be done, each and every day. 

Don't wait for the results to somehow make you confident...Instead, invest in the work and watch your confidence increase.
