People are always going to have an opinion about what you should or shouldn't do and how you should or shouldn't do it. Its normal... A lot of times, its coming from a place of love and concern. But you're the only one who knows what feels right to you. Yes, people can give great advice, yes sometimes you won't see what others see from the outside looking in and yada yada yada... And there's nothing wrong with taking what people say into consideration. But the decision is yours at the end of the day.
Sometimes people get upset when others have something to say about the choices they make but a lot of times, its because they have doubts themselves and hearing it from other people makes them feel like they probably made a mistake. But if you're confident that you've made the right choice; if you've weighed the journey and the outcome and you've come to the conclusion that you're on the right track, then that's all that matters coz you're the only one who will be responsible for the consequences of your actions; good or bad.
And when the consequence is good; and it leads to happiness, then all the better. There's a peace that comes with finding happiness whether its in a career choice, a business, a hobby, a relationship etc. And what people do or say won't matter because you're happy. If you don't feel that peace, then maybe you need to re-evaluate some things. But if you do, don't let the fear of whether it will last or not creep in, just bask in it and I truly believe like a seed, it will continue to grow. It doesn't mean there won't be challenges along the way, but it will make overcoming them worth it.
