Day begins with hopes and ends with a dreams!
Everyday starts with some expectation but
Everyday surely ends with some experience.
That's life.

But apki smile nahi to amara sms waste.

Self-trust is the first secret of success

‘મારા બાપા ખરું કહેતા હતા’ એવું માણસને જ્ઞાન થાય છે ત્યાં સુધીમાં તો એનો દીકરો એવું વિચારતો થઈ ગયો હોય છે કે ‘મારા બાપા ખોટા છે.’ – ચાર્લ્સ વર્ડઝવર્થ

જીવન એક બાજી છે, જેમાં હારજીત આપણા હાથમાં નથી, પણ બાજી રમવી આપણા હાથમાં છે.

એક સાસુમા ના ૩ જમાઈ હતા.તેમને બધા ની પરીક્ષા લેવાનું નક્કી કર્યું.

એક દિવસ..પેહલા જમાઈ ને બોલાવીને પોતે નદી માં ઝંપલાવી દીધું.પેહલા જમાઈ એ તેમને બચાવી લીધા અને સાસુમા એ તેમને કાર ભેટ માં આપી.

બીજા જમાઈ ને બોલાવીને પણ તેમ જ કર્યું.બીજા જમાઈ એ પણ તેમને બચાવી લીધા અને તેમને સ્કુટર ભેટ આપ્યું.
…..પછી વારો આવ્યો ત્રીજા નો.તેણે વિચાર્યું કે જો હવે આવું થશે તો મને બચેલી સાઈકલ મળશે. તેથી તેણે સાસુમા ને નદી માં ડૂબવા દીધા. તેરમાં ને દિવસે ૩જો જમાઈ નવી હોન્ડા સીટી લઇ ને આવ્યો ત્યારે બીજા ૨ ની આંખો ફાટ ફાટ થઇ રહી..હવે કહો આ હોન્ડા સીટી કોણે અપાવી ??.

All glory comes from daring to begin

Never mind what others do. Do better than yourself. Try to beat your own records everyday and pray to God for a better tomorrow

Success is more permanent when you achieve it without losing your principles.

WE CAN ALWAYS CHOOSE TO PERCEIVE THINGS DIFFERENTLY. YOU CAN FOCUS ON WHAT’S WRONG IN YOUR LIFE OR YOU CAN FOCUS ON WHAT’S RIGHT

Love is Precious Gift of GOD. Life is full of Love and Joy. We just need to free our inner selves, need more attachment with nature, feel the rhythm of Love and every moment of our Life. If we do so, we can easily touch the soul

You want and you get, that is luck.
You want and you wait and, that is time.
You want but you compromise, that is life.
You want, you wait and you don not compromise that is SUCCESS.

Love is a gift. If you receive it, open and appreciate it.
If not, don not worry. Someone somewhere is still wrapping it for you.

 Luck is not in your hands. But work is in your hands. 
Your works can make your luck but luck can not make your works.
So always trust yourself.

You must be the change you wish to see in the world

You can do anything, but not everything
