Being an adult and acting like an adult are not the same thing. Some people, even having reached a respectable age, continue to act irrationally and frivolously. If you want others to take you seriously, trust and listen to your words, change your behavior.
Instructions
Step 1
Determine what exactly you would like to change in your behavior. After all, there are character traits that are usually inherent in children, which would not hurt to have adults. This is spontaneity, curiosity, the ability to enjoy the little things. You are unlikely to make your life better by destroying them.
Step 2
Childhood does not pass without a trace, and in the depths of everyone's soul there is his inner child. But for some, he wakes up only occasionally, and to others he constantly dictates his behavior. You can calm him down, like an ordinary child, by switching his attention to something else. Agree with yourself that you will stop being systematically late for work, and for this you will buy yourself a house for a Barbie doll, a radio-controlled helicopter and a set-top box. And you will only do your toys in your free time.
Step 3
Start a diary and write down all your tasks for the day, preferably with an indication of a specific period of time when you will be doing this. This will force you to work quickly and complete your duties on time, rather than postponing everything until the last day. After completing the task, cross it off the list. You yourself will soon begin to enjoy watching how things get less and less.
Step 4
Learn to take responsibility for your actions. As a child, parents usually ended up forgiving the offending child, but your boss or supervisor is not obliged to do this at all. If you have already stumbled, have the courage to admit that this is your fault, and indicate the time in which you can fix everything, and do not tell that the dog swallowed the flash drive with the thesis.
Step 5
The surest way to start behaving like an adult is to rent a separate house and earn money on your own. This will teach you responsibility for your life, because now your well-being will depend solely on you. And, perhaps, you will like it so much that in the future you will want to take responsibility for someone else.
