Why do you want this?
Write down at least a few reasons why you want to achieve a certain goal. For example, if you want to get in great physical shape, name the specific things that you would like to successfully cope with after reaching your goal: easily run 5 kilometers, do 50 push-ups, or do splits. This will help you track your progress and strive for something easily measurable, rather than pursuing abstract goals (I want to be healthy, athletic, and so on).
Set a bar for yourself that really suits your capabilities. This way you can strive for what you can truly achieve. For example, you shouldn’t set your alarm at 6 am if you hate getting up early and are used to getting up no earlier than 10. When setting unrealistic goals, the chances of failure are extremely high. You will quickly lose motivation and become frustrated with yourself. So, accept the fact that big change is the result of small victories you make every day. For example, when looking to get up early, a smart first step is to set your alarm just 5-10 minutes earlier than usual.
Take a look at your excuses
Excuses are both man’s best and worst friend. The trick is that you need to evaluate them critically and understand the real motives behind them. Do you really feel tired to go to workout? Or do you just want to watch the new episode of your favorite TV series faster? If you find yourself using excuses to give up important tasks, adjust your behavior and take the action required of you. Yes, sometimes it will be extremely difficult for you to resist the temptation, but as you continue to exercise discipline and make the right choice, you will eventually forget about such a concept as excuses. However, if you choose to genuinely believe in the reasons for your excuses, you can never change your behavior.
