Tell us a bit about yourself. Are you more of a hunter or gatherer?

I’m a visionary and strategic person who values loyalty & integrity. I’m a combination of gatherer and hunter depending on context. I can think on my feet and solve problems, I’m vocal and practical person. I value my time with friends and family but also appreciate my own space to think, analyse and self reflect. I’m not known for being patient but I’m resilient, passionate and determined.

What motivates you to live a more eco-friendly lifestyle?

Mostly it’s about saving money and then my love for God encourages me to take care of the environment and do my best to not destroy it.

What’s your signature eco-friendly habit?

Reuse, reduce, repurpose and refuse ….I try to avoid wasting of resources by all means because I’m frugal person.

If we came over for dinner, what would you serve us?

Lots of Meat, vegetables and cake …I also love pasta but I do enjoy my meat with some fat on it. If my daughter is cooking, you’ll defiinitely get pasta/ burger/ sandwich with fries or green salad with ice cream for dessert. 

Do you make sustainable choices while traveling? Tell us more.

I love traveling! I never really pay too much attention to fuel emissions when considering my flights or driving, but I try to be environmental friendly by not littering or buy unnecessary stuff.

Do you opt for sustainable clothing and beauty products? Any favorite shops or brands?

Starting to get the hang of it when it comes to clothing because I’ve been exposed to circular textiles, but no I don’t really have favourite brands yet. Learning about circular economy opened my eyes and helped me to pay attention to sustainable products but I’m not fully there yet 

What’s the most important environmental lesson for kids today?

Be environmentally conscious and think about future generations, whatever you waste today might not last you long enough. Don’t waste resources and please don’t litter – its much easier to keep space clean than tidying up.

What brings you joy and how do you find peace?

Beach walks, reading, traveling to new exciting places, spending time with my loved one’s and having positive impact on people’s lives. There’s more joy in giving than receiving but don’t neglect yourself in the process, hence I enjoy staying home with my daughter and doing nothing when time allows.
