More generally, take the rest of your twenties to explore and push. You have (I assume) no child care responsibilities and its a good guess you wont till thirty-ish (if it changes - great !) - so can I recommend the following plan:
0. Unemployment is rife across Europe, especially at your age - so if in two years you have not had a "proper" job, it will look no different than 50% of the rest of the continent. But if you have run a startup, consulted, travelled... well...
1. With a degree in electrical engineering you have a massive advantage over most startup entrpreneurs - hardware.
2. Go look at the hardware hackday running with ycombinator (cannot find the link - on iPhone - anyone?). It might give you some ideas.
3. Market yourself as a prototype maker - join some maker groups, get some experience with arduino's etc. Maybe the local fashion college has people wanting to experiment with wearable fashion (plus point here - fashion students throw much better parties than EE departments)
4. Start talking about this - in English on a blog. Include youtube videos of the wearable stuff.
5. Want to travel - then stick to the hardware theme. DO the young backpacker thing, but ask on HN for contacts in Shenzhen and Mumbai. Go meet some folks and make contacts / friends. Be the Belgium hardware consultant with contacts in the hottest hardware and development hubs globally. Blog on your travels, and if you can, do some arduino prototyping and consulting - getting paid to develop a startups new wearable toy whilst actually in Shenzhen. Better than paying yourself. And stop off in Goa and dive in Thailand - just because you need to relax.
In the end you are young - enjoy yourself. But be smart - enjoy yourself and at the same time build valueable skills. You already have a massive edge - increase that edge.
Remember you are a rare commoditity and investment money is dirt cheap globally - so if you need to raise cash later on you are the prize for them to compete for.
