First of all congratulations on joining the plant side!
The first year can be tough but it you've made up your mind and that's going to keep you strong! I would suggest always having a back up cliff bar or some nuts and seeds in your car. Or if you know that you are going somewhere that has slim options to just snack before hand.
Also try to be the one that makes the arrangements, if you find a few restaurants that have some veggie options then recommend that yall meet there for a change.
Or show off your new plant cooking skills and invite friends over to your place for dinner!
I wouldn't worry about trying to talk people into going vegan with you, instead just be a beacon for the plant based movement. Let your actions and your energy do the talking.
I would highly recommend checking out 'Rich Roll'. He is a plant based athlete that has an amazing podcast and his wife just recently came out with a vegan cheese cookbook, called 'This Cheeze is nuts!'
Again congratulations on all the positive change that you have embarked on and keep it up! I'll definitely be following you!
Thanks for your comment and inspiration @jeremiahsvaren. I'm keen to follow you also as I love having positive and inspiring people in my feed. It's actually my birthday today and my wife booked us into a local vegan restaurant, how awesome is that! I will take your tip on board and try to keep some snacks handy. I'm not a big lad thankfully so I'm sure having a bag of nuts or a bar stashed in my car could really come in handy. I'll look up Rich Roll, sounds very interesting and every bit of information I can get really helps :)
