Two Points
Newton
In my opinion, Newton's third law, that for every action (force) in nature there is an equal and opposite reaction, doesn't only apply to physical phenomena, it applies to your life too. This is not an original thought however, it bears repeating. The value you put into the world will always be rewarded in-turn. You may not see it straight away but rest assured, it will be. Similarly, the toxicity you put into the world will also always come back to you in one way or another. This idea goes really well with the next...
Everything is your fault
The idea that everything is your fault is not necessarily true but it is a mindset that will set you free.
Some might find it harder to adopt this mindset than others but it can be extremely powerful for all.
The reason you should have this mindset is that it creates accountability for your actions as you navigate the world around you.
Why are you an alcoholic? Because you drink alcohol. Why are you a smoker, destined for lung cancer and a small bank account? Because you smoke.
It's not the government's fault, it's not your overweight girlfriend's fault, it's yours.
People try to rationalise why they are in deep ruts or bad places in their lives when if they just took some accountability, things could change.
It's imperative that you're aware of good things in your life happening because of your actions as well!
Unfortunately we can't say they are your 'fault' for semantic reasons but effectively, they are.
Even if you make the case that the environment around you made you an alcoholic, or your genes are the reason, blaming it on those things will not set you up for future successful change.
It may be true that something is not your fault, but is is bad for you personally, to always blame and not be accountable.
As you adopt this mindset you start to realise that actually a lot of things are your fault, including the good and bad things in your life.
You start to see others outcomes, not as lucky or unlucky, but as the sum of their lives actions.
No, this is not an absolute truth but it is a general rule when thinking introspectively. For example, other peoples actions are generally not your fault, they are theirs.
There will always be exceptions and I'm not auguring that everything is actually your fault, I am saying that it is the best mindset to adopt.
It's similar to the power of goal setting. Goal setting puts your subconscious mind to work and guides your everyday decision making.
This does the same, just with another facet of your psyche.
It allows you to celebrate other's success and be truly proud of your own.
Otherwise, risk thinking that others only became successful because of other people or that they just got lucky... A tell-tail sign of a butt-hurt individual who has zero accountability for their actions. If you ever find yourself thinking or saying this, it is a RED FLAG, dude.
So shift your mindset today, take responsibility for your actions, remembering that the good you put out will always come back to reward you in some fashion, and always in an equal proportion.
