Start small: Since you lack self-discipline and wish to generate it, like any learning process, start small by taking incremental actions in the direction of your ultimate goal. Make sure these “actions” are easily and quickly attainable.

2. One step: Try selecting just one thing to do at a time. This will help keep your focus and sense of accomplishment when finished. Immediately upon completion select a new goal to accomplish, do not allow complacency to set in.

3. Listen to yourself: One thing to be cautious of when endeavoring to change your undisciplined nature, is to consider whom you are surrounding yourself with? Are these people negative and also undisciplined?
 
4. Weak moments: One of the trickiest parts of learning self-discipline is handling your mental lapses and weak moments. Be cognizant of these mental lapses and work through them.
 
5. Fit your lifestyle: To improve self-discipline, you must make whatever you've decided to do fit your lifestyle. No matter what you do, a round peg will not fit into a square hole.
 
6. Stop talking: Very often when we make up our mind to do something, we start telling unaffected people what we intend to do. Try not to do this and just get on with the action at hand. These people will see soon enough what you are doing.
 
7. Milestones: Set goals and milestones. It can be hours, days, weeks or even months. Write your goals and milestones down, if even noting how you feel each day. Make an entry every day regardless how inconsequential you think it might be.
 
8. Everyone slips: The biggest threat of losing the self-discipline battle is slipping and then sinking straight into defeat. This is very common with dieting and eating that first cookie or missing that workout routine. You are human and lapses occasionally happen don’t punish yourself for it.
 
9. Reward yourself: As with almost everything in life, when you reward yourself, you will find that your sub-conscience will start to be your ally rather than a subversive adversary.
 
10. Write: Make a commitment to start journaling and reading your daily entries every day. This in itself can lead to self-discipline since this commitment is exactly that, self-discipline.
