How can we achieve our goals ? - My opinion

In some cases, if we want to achieve our goals we need to be more productive. To be more productive we must to act according to a mindset (What mindset? You must tell what mindset you are talking about.). So, if do you want to be more productive it's ok to have the correct mindset(Ok is not a very strong word. You probably mean that it is good to have this king of mindset. Saying that it's ok in this context means that it isn't very important.) that to help you. My mindset when is come to achieve my goals is very simple. My mindset is simple: to acheive my goals. In brief Basically/Simply put, I have in mind two ideas in mind, that help me to remain focused on what I want to do.

Here are my 2 ideas:

1. If you want something, you need to give up something else.

2. If you want to have what you don't have, you need to do what you aren't doing.

Example:

If you want to be more healthy you need to give up eating junk food(1), and start making playing/practicing more sports (American English, sport is acceptable in British English).

If you want to complete your tasks, You need to give up that activities that distract you from completing your tasks (1) and start doing whatever it takes it's worth for to complete your tasks.
