Be optimistic: Optimists always figure out the light positive of negative events.

Organize your priorities: You have to categorize your tasks into groups ( the most important tasks, the important tasks, and the unimportant tasks)
Time management: You should be able to plan and organize the hours that you spend in doing your tasks.
Maximize strengths: You need to know your strengths ; this will help to discover your potentials.
Minimize weaknesses: You need to know your weaknesses and try to improve them.
Practice positive self-talk: try to talk to yourself positively ( ex: I am not lazy,I am successful, I can do it...etc)
Try again: If things don't go alright, you have to find another way until you accomplish your goal.

I hope that these tips are beneficial for you. :)

Action. The key to learning language or any other positive action is to quickly make small improvements.  Paralyzation is to know what language or goal we want to learn and doing nothing. Now do the opposite. Don’t plan or research until taking action.  Most of the time, planning is procrastination.

Try to figure out what makes you like this and try working on it .. For example if you seem to tell yourself negative talking like(i'm a loser, i can't do anything) your miind translate this like it's a real talk and this affect and reflex your behavior, Try being more positive, start with something you like to do then move to your homeworks or whatever you want to do, And if it's something else try to solve it first.. Think a bout your future and the time you going to waste if you still like this

P.S. i'm a lazy person too but i decided to change and i started all you have to do is start & GOOD LUCK 

Please, I need some advice.

Thank you...
