Hello and some questios about the technology tree

[radicaled]

Hey guys, I just started playing ksp and I have a ton of questions.
But I would like to ask about the technology tree, I don't want to mess up more than it is now.

I don't know which technology should I select. I'm incline with the fuel system.

Think of the next mission you want to do, and select the techs while will allow it. If you have the techs you need, hold on to the points until you need to buy a tech. 

And welcome to the forum.

Well, I would either look at boosters, wheels, or solar panels, with science technology also being high on my list. I usually find it easier to wait until I have enough science for two nodes so it's a bit of an easier decision.

Also, welcome to the forums!

Welcome to the KSP forum @radicaled New here myself since the end of last year, but yea so much fun with KSP and this forum. 

As far as the tree is concerned, just balance it the best way you can. I usually do rocket stuff so a nice even balance between engine sizes, tank sizes, how many Kerbans you need to do and so on. I always pick fun stuff to do from the contracts from Gene Kerman and then look at the tree and what I need to accomplish in it. I always take tourism as a plus even though there is no science. It builds up fast for kerbucks, then I always go to parts testing for great science.

I hope you have fun.
