what habits you should get rid of by the age of 30 ..

Chasing Dopamine
If you live your life chasing a high, you will never be happy.
You will be forever addicted to whatever gives you short term satisfaction e.g tobacco , alcohol, and excess social media usage.
Invest in the good kind of dopamine addiction if you have to, the kind you get from working out for example.

Forcing Incompetence
People like to say things like “I am bad at math” or “I am bad at languages”.
Just because you’re not naturally gifted in an area doesn’t mean you’ll never be able to learn those skills. anything can be learned if you put your mind to it and try to copy it at the slowest speed that is comfortable for you.
You should try different ways of learning something before you throw in the towel.

Being Risk-Aversive
It can be easy to avoid risks and fall into your comfort zone.
The biggest risk in life is not taking any.
Don’t let life pass you by and regret that you didn’t do something later in life.
Take a leap of faith and enjoy the highs and lows of life. They won’t kill you.

Mindset of Victimhood
If you constantly blame others for your failures in life you’ll 100% never grow.
Some circumstances may be out of your control due to incorrect timing and outside forces.
There is no point in directing your anger on others, you are the master in your life.

Multitasking
We all like to think we can multitask, don’t we?
But multitasking is actually less productive than focusing on one task at a time because you’ll make more mistakes, which is counterproductive ultimately.
Break the habit of multitasking and you’ll observe that the quality of your work will improve.

Perfectionism
Thinking “If it’s not perfectly done, then what’s the point of even doing it?” is extremely destructive.
You’ll lose motivation and waste time on unnecessary tasks trying to find reasons why “it” should always be perfect.
The best way to approach this is by simply starting and trying something the best way you know how and doing a quality test at every checkpoint to see what’s working, what’s perfect, and what needs adjusting. That way, you’ll be benefitting from the end goal indirectly and you be documenting your journey in terms of do’s, don’t’s, highs, and lows.
So don’t let perfectionism get in the way of your goals.

Neglecting Self-Care
Take care of your body, mind, and spirit.
Focus on your diet, get a good night’s sleep, drink enough water, get enough sunlight, and exercise quite often.
Do not work extremely hard until you’re burned out. Eventually, all that hard work will be pointless if you clock out of this life before you’ve seen its fruition, won’t it?
So take care of yourself because your life literally depends on it.

Fearful Mindset
Thinking about the worst possible outcomes when making decisions or taking risks is no way to live.
It’s very difficult to achieve anything worthwhile with a pessimistic view of life.
Everything orchestrates and begins in the mind and then manifests itself outside.
