Hi!,

I have been there! Do you know any computer programming or scripting language! If not, start with a Linux or awk tutorial. There are several very user friendly bioinformatics tools. Install them into your computer, choose a project and try to analyze some sample data. Get some NGS data try to analyze it. If you do not have it yourself, try to download from publications or sample data from Illumina website. Start with simple things such as check sequence base quality, genome coverage, estimation of insert size, etc Following three bioinformatics tools will give you a good start: bedtools, samtools, bamtools. You can check official documentation for installation, if you are using a mac computer, here is a page explaining how to install them: http://genescripts.com/

Just try to use each command and figure out what they doing. You will learn a lot. Visit forums like this and read them. Try to take free courses online from Coursera, Mitedx, Udacity, etc. A great public tool is [Galaxy project](http://galaxyproject.org/). There are many tutorial video there. You will learn a lot. Have fun during your studies!
