Hi,
Don't get pessimistic about self, you have got good height so try to improve yourself by making slight efforts for making self more confident, be an optimistic person as it will attract people around you, be a good communicator which enhance your personality, do little bit of exercise daily which will also contribute in that.
So what if you are 34yrs. of age, you can still get married! There is long way to go...get indulge into those activities which will enhance your inner talent...try to find out; it can be singing or dancing or painting or writing or anything. Don't lose hopes as 'God helps those who help themselves!' There is nothing impossible!
Keep an aim in life. Work hard to achieve your goal in personal and professional life both.
Make a list of both your positive and negatives points , work on to make positive points more. Plan how you will do and when you will do it; makes good friends and be with your good pals who can guide you, take their help as they will hold your hands in time of need.
There is always a silver lining with every cloud!
At last, but not the least, 'Be a Good Human Being!' People adore good humans.
All the very Best!!
