Dr. Bernice Andrews from Royal Holloway, University of London, conducted an experiment on about a hundred middle-aged women; 79% of them had low self-esteem and depression. She wanted to find how they changed over seven years. The follow-up research revealed that only 4% of the women still had the same diagnosis, which indicates that people can surely change, whether it is due to different environments or certain events. We’ve seen irritable people becoming gentle, and passive people becoming assertive; so it makes sense.
So you don’t have to feel disappointed just because you don’t like your personality. There is room for change as far as you don’t give up. It’s okay even if you lack willpower. It is said that most people eventually accomplish what they have delayed when the right environment and opportunities are provided.
We constantly face environments and opportunities to change our personalities by reading and listening to the word of God about what personality traits we must obtain to enter heaven. It’s much easier for us to change than not change.
“Through these he has given us his very great and precious promises, so that through them you may participate in the divine nature and escape the corruption in the world caused by evil desires. For this very reason, make every effort to add to your faith goodness; and to goodness, knowledge; and to knowledge, self-control; and to self-control, perseverance; and to perseverance, godliness; and to godliness, brotherly kindness; and to brotherly kindness, love.” 2 Pe 1:4–7
