Why you are unable to motivate yourself even after doing everything you can?

The Internet is filled with motivation stuff, inspirational quotes and aspiring people. Yet almost all of us are unable to keep the motivation going. We are unable to stay determined. Failure means an end to a dream to most of us. Today, I am going to help you to analyse why this happens to us and how we can help ourselves in this situation.

                                   PROBLEM

I'll directly come to the reason behind this. The first reason that comes to my mind is that it happens because we see all these stuff way too often. In the earlier days, when there was no internet, people used to change themselves for their whole lives by only reading a single quote. This was because words had lasting effects on us. We were not bombarded with motivational stuff. Human nature demands balance of things. We can't handle anything that is in excess.
The second reason behind this is that motivation comes from within. You can always watch an inspiring video on Youtube to boost your mood but it can never motivate you for a longer time.

                                  SOLUTION

Solution to the first problem is that don't get involved into these motivational posts a lot. Watching them every once in a while is fine but making it a habit is the last thing you want to do to yourself to keep yourself motivated 

Solution to the second problem lies in your own hands. If you really want to motivate yourself, you'll have to do it yourself. Self talk is one way to do it. Talk to yourself about how you can pursue your goals or targets, how you should approach your life. Since you're deciding it yourself, you won't need an external influence to tell you that.
By simply applying these two easy to do techniques, I am sure you can achieve your target.
