Do you think life is more beautiful than it is ugly?
Life can be beautiful or ugly, depending on the perspective you are coming from. Considering your choice of wording in setting up the question, I presumed you will like to think life is more beautiful than it is ugly. Of course life can be cruel. Earth is not exactly the best place to live as it is full of sufferings and ugliness. But I find this one trait particularly helpful to bring my perspective back in line whenever I swerve away from the thought of the life being beautiful:
Yes, by practicing even 1 minute of being thankful every day, you will see life unfold more beautifully as you carry out your daily works. Being thankful for everything that has happened, either to mold you into becoming a better person or to teach you a precious lesson. Being thankful for all the possessions you have acquired, count your blessings, even the fact you managed to wake up this morning and breathe well.
You will start seeing life a little differently.
