Todays' Thought
The lack of a degree is actually an advantage. If you are an engineer or a doctor, there is only one job you can do. But if you don’t have a degree, you can do anything.

किसी डिग्री का ना होने दरअसल फायेदेमंद है. अगर आप इंजिनियर या डाक्टर हैं तब आप एक ही काम कर सकते हैं.पर यदि आपके पास कोई डिग्री नहीं है , तो आप कुछ भी कर सकते हैं |
