To be honest just like starcraft it's all about mindset. You need to focus on your goal and believe in yourself to achieve.
Many have the mindset of "going on a diet" or "going to the gym". If it seems to be a chore then obviously your not gonna have a positive attitude about it for a long period of time. If you want it to sink in you need to change your mindset about it. This should be a "lifestyle change" where you decide to eat clean and exercise as your normal life routine. This is the only way to remain consistent compared to those who I see at the gym who has spurs of few months where they go and then they idle for most of the year. I think the same principle applies when taking supplements.. "fat burners", "test boosters". These are just like taking a shortcut, they may have small effect but again should focus on making it fit into your lifestyle, taking shortcuts just leaves you susceptible losing motivation. The only thing I take is ISO 100 protein sometimes and multi-vitamin. I strive to get protein from diet rather than using supplement in most cases.
As it has already been mentioned its primarily about diet, food intake! There are many apps for mobile phones / computer that can help you count your calories/intake based on goal and what breakdown of foods you should have. Personally I do half an hour gym sessions which are 4-6 reps, 3 sets of heavy weights. Generally you will find for building muscle heavy weight is better, but make sure you practice and get technique correct first. As soon as you get close to lifting 6 you go up in weight and aim for a least 4reps!
TL;DR
Make a lifestyle change, set goals, eat clean, lift heavy!

This is going to be an area of contention, but assuming that the OP hasn't lifted before, starting out with low rep high weight sets could be counter-productive. Personally, I'd recommend starting out doing the stock-standard 3 sets of 10 reps and not bothering about anything like pyramid sets or drop sets or even low rep sets.
Until form has been ingrained into the OP's mind, lifting big could result in injury and even tearing in certain muscle groups like hamstring and forearm.
In the end OP, it's up to you to decide how you wish to start, but until you have a solid base in how to lift properly, I'd very much recommend you start with lower weights and really focus on solid form. Lifting small weights to get started is nothing to be ashamed of - people who go to the gym would rather see someone under-lifting at first instead of piling on the weight and arching their back because they can't lift it.
