Success is not achieved by accident or luck. It is the end result of hard-work and dedication. Even so-called overnight success stories usually happen because someone spent years educating themselves and building relationships so they could be "in the right place at the right time".
It does not matter who you are, where you are from or how much education you have. If you start making daily progress towards your goals, and never give up, even in the face of failure, you will eventually achieve those goals.
The concept for success actually looks incredible on paper. It involves four basic ideas.
1. Setting/visualizing your goals
2. Prioritizing why you want to achieve those goals (You MUST have a reason "why")
3. Re-structuring your daily habits to coincide with your goals.
4. Never Give Up, no Matter What!
Now, as simple as it looks, actually putting those ideas into action - especially the third and fourth parts - is where it becomes difficult.
Some people will never sacrifice enough in the present to get what they want in the future. Unless they are blindsided by luck, those people will never achieve the level of success they desire.
It is not enough to just want to achieve success, you must indentify specific goals, have a driving reason why you want to achieve your goals (taking better care of your family, having financial or time freedom) and take action every single day towards those goals.
The amount of success you achieve is directly related of the amount of changes you make in your daily habits coupled with persistent action.
