Once you have taken the time to learn about yourself, you may find some dirty laundry and hidden scars that you probably would have rather kept hidden. Unfortunately, you have been wearing these scars every day in the way you interact with those around you. These scars could have made you too soft to express how you feel or too cold to care about the feelings of others. Now that you can see yourself clearly, become the best version of yourself. Love yourself. And above all else, be true to yourself. Knowing your limits is another important skill to master in order to navigate through this crazy world successfully.
Once you have a carefully thought out plan that will allow you to care for your responsibilities and still venture into a field that you love, go for it. It might be a case that money is tight and you are already strapped for time and may not be able to make a move right now. But I would encourage you to continue preparing yourself. Keep learning all that you can about that career online or from the people around you. That way, if the opportunity should arise, you will be in a position to take it.
