Explain to your family that becoming a traveler is a very professional job and show them videos n photos of very big professional travelers of the world.
1. Do not give up on further studies. Because you cannot pack in the day job atleast 2-3 years at the start of your travel journey.
2. Learn the skills and be original, do not copy.
3. Seek to make a difference rather than doing it just because it seems like a fancy life.
4. Understand social media platforms.
5. Give yourself the chance to explore your real passion and strengths. And then only pursue the things that actually makes you happy.
6. And most importantly, just start travelling. Take a trip and just go with the flow. You learn the most with experience and you'll come back from a trip with tonnes of knowledge on how to travel better the next time and where does your heart really lie.
As you are beginning to explore your new passion. You have to first give it some time to see if this is just a hobby or you can actually earn a livelihood out of it. I would recommend to keep studying the best subject/steam you think you can concur easily and can see yourself doing a job in that field for at least 2-3 years.
Even if your passion is travelling and blogging, you can keep your degree as your earning option when you can't earn anything from blogging and keep figuring out the ways and tricks around vlogging. Later in life if you feel vlogging is actually earning you your livelyhood, you can stop doing other job and make vlogging your main thing. Keep in mind vloggin will have more ups and down earning wise than your job. so keep doing your vlogging with whatever you time you have apart from your studies and job. Having a good degree in normal streams is easy to get and college time will give you much more time to explore your vlogging and travelling passion.
