Realizing your dreams is not a matter of possibility; it's a matter of motivating yourself to focus on the right things. You know you should be doing something, but sometimes you just don't feel like doing anything. This discouraging situation can last a long time if you don't head it off and take action. Here are some daily motivation tricks that might work for you.

小题1:      

This is by far the most important tip in this article, because in the end, all of the other tips in the world won't make as much of a difference as this simple and timeless instruction: Sit down and get a move on! Do you feel the push-back of laziness? Reading more about motivation won't help. Reviewing your to-do lists won't help. Only doing actually helps get everything going. So stop thinking about how hard the task is going to be or how long it's going to take you. Not starting is failing. Tell yourself, "As soon as I get going, I'll feel more motivated." And you'll realize it's not nearly as hard as you thought it would be.

小题2:      

Be aware of your self-talk and stay confident. You have the choice to replace negative self-talk with a more encouraging and friendly voice. A voice that will consider your aim as not just a possibility, but a probability; A voice that does not look at the possibility of success before taking action, but rather uses self-belief as its driving force; A voice that all things are possible to those who commit to their dream.

Tell yourself over and over again that you can do it. See what effect it has. Persist with this kind of possibility and eventually you'll feel better about whatever it is you want to get done, and you'll even start to fool yourself into believing it's true.

小题3:     

There is no better way to recharge yourself for improvement than spending time with someone who motivates you. They are smart and can always encourage you to be better. Study their qualities. Study their habits. Surround yourself with them, talk to them, learn from them; they are already living and producing results at a level you admire and expect to. Compare stories, successes and failures. Let their inner light guide you.

小题4:     

You have made so much progress, you just don’t realize it. Open your eyes and give yourself credit for all that you have done. Think about it. Write down your past successes. Consider using a journal to keep track of them. You’ll probably be pleasantly surprised when you review your results. It’s a great motivator to see how much you have improved and how far you have come. Be happy with your progress and move on.

小题5:     

Do not judge unsuccessful attempts and mistakes as an indication of your future potential, but as part of the growth process. Something does not have to end well for it to have been one of the most valuable experiences of a lifetime. When times get tough, take a deep breath, and know that most great things come when you least expect it. Being defeated is a temporary condition; giving up is what makes it permanent. And most people that gave up didn’t realize how close they were to success. Push through!
