Society has its own way of looking down on people. Even though you've done a lot of good and helpful things, with a motive of improving a certain situation, none of it will matter as soon as you've committed a single mistake.

You might find it difficult to adjust since you will be easily judged and criticized by many. Doubts will consume your inner thoughts, putting you in a state where you'll ask, "is this even worth it?" in everything that you do. So instead, do any good thing without minding what would other people react, say or think. This way, you'll be able to contribute a lot without having to think about the negativity that fills your surroundings.

Most importantly, try doing everything for the Lord. When you do something dedicated to and pleases God alone, there's completely no judgement. Also, even though you've done a lot, you won't be feeling tired and lowly.

People might put you down, discourage you, tell you that everything you do is completely and utterly useless, but as long as you know to yourself that you aren't doing anything wrong, don't be afraid to pursue it and keep on going!
