In short - there are no quick-fixes, no magic powders or potions to being in shape. Even surgery and implants are painful and take time to prep and recover from.
Here's my advice:
1) Have some short, medium and long term goals that are achievable
2) Stay focused and don't lose motivation or hope if you don't quite hit them - progress is progress
3) Get a professional's help/advice - this could be just an instructor at the gym or paying for a Personal Trainer/Coach. I cannot stress how important it is to be taught by someone that is accredited and knows what they are doing! Technique is more important then putting more weight on the bar, no matter what the people in the gym/your ego tells you.
4) Make a plan of your week, when you can train, when you are going to rest (again, another key factor that most people miss - more is not always better!) that is realistic and you can stick to.
5) Understand your diet, what nutrition you need, how much fluid you need to take it - keep a food diary and work out what you are lacking. You don't need protein shakes if you eat right. Learn what proteins, fats and carbohydrates are, what they do and how you can get good, clean sources of them.
6) Plan your meals for the week (and prep if you can). This will not only help you to know what you're shopping for but will also help to keep costs down as you will only be buying what you need and then not wasting anything, or be tempted to put something else in your shopping bags!
7) Take Creatine Monohydrate
8) Keep progressing your workouts - change the intensity, change the lifts, change the order, change the weights, change the time under tension - every 4-6 weeks. I work through periods of Stability, Muscular Endurance, Hypertrophy, Strength and Power. Don't let your muscles get used to things!
9) Eat! This is the biggest thing - I would rather miss a workout than a meal because training without the right fuel can be just a detrimental to your goals. Again, refer to #3 for more information - with the best will in the world, asking big and vague questions to strangers on the internet will never give you as good an answer as speaking to someone in person that can give you the right info specifically for you!
10) Stick with it - there is never perfection, only progress! Don't judge yourself against anyone else other than the person in the mirror
