Thinking to start something? But don’t know how to start?

I have set a goal for myself since I was in 9th class, that, I will do CSS. Now I am in Master's. But I haven’t done anything for so long to get closer to achieve this goal. I just have been wanting it like a fancy dream but haven’t put any effort to get prepared for it. Maybe I was looking for a perfect time to get started and most probably I was procrastinating because I had enough time to get started for it. But now, when I realized that I am left with just one more year and a half to take my 1st attempt of CSS; I am exhausted. I am thinking for all the past years that I have wasted seeing dreams only and not actually working for it. But I have also realized that sometimes it’s now or never. We should not wait for the perfect time as there is no perfect time. We should take the moment to make it perfect and productive. I have decided not to waste any single moment anymore. I have said goodbye to procrastination. And I have started working on this goal to make it happen. I have downloaded the GRE World list and started cramming it. I have started my Islamiat and GSA syllabus. I have started reading the newspaper. This is my just start experience. This is quite tough at the start as my mind is still forcing me to procrastinate. I have to be more responsible and punctual to cover all this syllabus. It has taken me out of my comfort zone. I still don’t know all the strategies to follow to achieve this goal. But I am letting my just start experience to guide me to the rest of the plans. Nobody knows how things will work out when they start something and think about how they should start or when to start. Just start and then let the work teach you itself.
