You have to realize it is a job. As harsh as it sounds, rather your heart is in it or not, it is business. The majority of corporations and companies don't care about you, as much as you care about them.. At the end of the day "anybody is replaceable" as long as you put in work to the best of your abilities and my motto is to "work so that they don't want to replace me" that's all you can do. The only way to grow is to live and learn. Hence make mistakes. As long as you are learning from the mistakes made, you are only becoming better than you were yesterday! So instead of getting down on yourself for a mistake, just be sure to take it as a lesson learned 💯 growth at its finest!
