Do you need to check the FB message first or do you need to check if there is an email from a client that may give you an income? FB is fun but all you can get there is fun, sometimes you even see posts that are stressful. Checking if there is an email form clients has no assurance if you will get an income but still the possibility is there. You should choose possibilities over non beneficial activities.
Are you going to watch the tv first or are you going to finish your assignments? Those little decisions are the deciding factor if your life will be headed in the right direction.
The reason why you are failing is because you don't know what should come first, you don't know what should be done first. All you know is you want to feel good at the moment by buying the things that you want but you don't necessarily needed and doing useless things that will make you forget that you have important things to do.
You have an assignment but you prioritize watching TV instead of studying. You have bills to pay but you choose to buy expensive shoes instead. You are the one who is putting your life in jeopardy. You make wrong decisions that makes your life harder and uglier.
Make adjustments to your decision making. Not all the things that feels good at the moment should be purchased. Not all the activities that excites you should be done first. There are things that are very hard to swallow because there is a sacrifice attached but when you do the most important things first...good things will happen later.
Yes it feels bad to choose the things that are important rather than choosing what makes you feel happy. But those things, those activities that replaces the problem will give you bigger problems later.
