Learning to trust the instincts and intuition you were born with takes a little work on yourself because from a young child we are programmed or condition to do this or that and not do this or that because it has implications. That might have been great when you were a child and you were dependant on your caregivers.
Now that you are an adult and are making your own decision it is important to examine that programming to see if it still serves you. If not it is time to change those bits that no longer serve you AND it can be done because you now have a choice AND the meaning you give those experiences or events in your life can be changed or reframed.
You may be asking yourself why would I want to do that?
Great question and here's the thing..
How you view those events and the meaning you attach to them will determine your values and beliefs and more importantly the choices you will make. Those choices are made in your unconscious mind based on your emotions and your thinking around them.
If you're still with me, they are your drivers and so are very important. It is possible that you are carrying beliefs about things that occurred when you were a child and you were not responsible for them and now you believe in some way that it was your fault.
Like your parents breaking up , abuse of some sort, being betrayed or abandoned just to name a few. In many cases they're not your fault at all , they happened to you and now it's up to you to decide what they mean.
This makes it possible to take the load of yourself and begin trusting your own intuition and self-belief again as it was meant to be. You have everything you need inside you now. You are not broken or incomplete, far from it.
Good news is you can change your beliefs and values if they no longer serve you. You aren't stuck with them.
Focus on what you want and bring those thoughts out into the daylight.
Give them structure and add appropriate emotions to them until they become real and tangible, so you can feel them and tell yourself what it will give you when you have realised that goal or outcome.
